Swedish brand takes the covers off its classy new flagship sedan

Volvo S90 revealed

Volvo has revealed the first details of its new flagship sedan, the S90, ahead of its official debut at next month's Detroit motor show.

The Swedish brand released a comprehensive suite of images of the classy-looking four door, but a limited amount of technical information.

The S90 is the second car based on the company's new flexible architecture following the XC90 SUV, which launched in Australia earlier this year. It therefore shares most of the seven-seater's mechanical hardware and underpinnings.

Volvo confirmed the S90 will have a plug-in hybrid variant, powered by its T8 Twin Engine set-up that combines a 2.0-litre petrol motor that is both supercharged and turbocharged with an electric motor. It has yet to provide details on the engine's outputs or fuel consumption, but it is expected to produce similar numbers to that used in the XC90 with 299kW/640Nm, the ability to drive up to 43km in purely electric mode and a claimed average fuel economy of 2.1L/100km.

It is expected that more conventional engine options will also be offered with either petrol or diesel propulsion, driving through an all-wheel transmission with an eight-speed automatic gearbox.

Volvo claims the S90 brings a host of world-first technologies, including an addition to its City Safety suite that detects large animals such as cattle and horses in any situation. It also comes equipped with semi autonomous driving functions that help steers the car through bends on freeways at speeds up 130km/h.

It also says the four-door's cockpit will be sumptuously appointed with the latest connectivity features, including cloud-based apps and services.
